I'm looking for a cheap (~40$) smart ring

submitted by binaryqueen to programming 19 points | 6 comments Good morning 👾 I’d like to fetch data via BLE (Python or Swift) from a cheap smart ring that can be reverse engineered or that is already RE’d. Pulse, oxygen levels, gyroscope, button would be very useful. I’d like to build a python or swift library. Thank you for any input =)
